My Achievements
Throughout my career, I have consistently delivered high-impact solutions and received recognition for my expertise.
Reduced application page load time from 7 seconds to 0.5 seconds
Token Metrics is a crypto analytics platform that displays historical data of cryptocurrencies such as Bitcoin and Ethereum, similar to a trading website. The website was initially slow, taking an average of 7 seconds to load the page and data. I redesigned and optimized the system architecture, introducing caching at different levels, including server-side and client-side caching, as well as request-level caching. As a result, the page now loads in about half a second (0.5 seconds).
related projectDeveloped a robust End-to-End automation testing framework
Nucleus.io (Acquired by ChangeHealthcare) was in need of an end-to-end testing framework that could test their medical imaging web app across different browsers and devices. I developed a robust automation testing framework using Cypress, JMeter, etc. The framework was able to test the application across different browsers and devices, ensuring that the application was bug-free and user-friendly.
related projectCreated custom server for obsolete medical device protocol
During the initial phase of my career, when I had only one year of experience, I was assigned a project to retrieve data from a medical device. The device was very old, and the company that manufactured it was no longer in business, leaving no documentation available. I utilized Burp Suite to analyze the data being sent by the device and created a server based on the obsolete protocol it used. As a result, the device successfully connected to the server, allowing us to access the data stored within it.
related projectCreated AI Model to parse bank statement PDFs for bank
"Cointribe" was developing a fintech product designed to parse customer bank statements and generate insights for banks or financial institutions. The project was initially handled by a different team that was unable to achieve the desired results. When I joined the project, I developed an AI model capable of parsing any type of bank statement within three months.
related projectBuilt architecture to send millions of email per day
While I contributed significantly to "contaqt.nl" version 2, my biggest achievement was enabling the platform to send millions of emails per day. Contaqt.nl was struggling with this issue, so I introduced AMQP and RabbitMQ to solve the problem. This allowed them to scale from thousands to millions of emails per day.
related projectBuilt Whatsapp bot for school ERP platform
MeraSkool.com needed a solution that would eliminate the need for parents to download any app. They wanted to remove the parent app altogether. I introduced a WhatsApp bot and built it in just one week. Now, parents receive student notifications on WhatsApp and can use it to ask for fees, pay fees online, get results, and more.
